The beta sheet, (β-sheet) (also β-pleated sheet) is a common motif of the regular protein secondary structure. Beta sheets consist of beta strands (β-strands) connected laterally by at least two or three backbone hydrogen bonds, forming a generally twisted, pleated sheet.

"WebSecondary Structures Proteins consist of a linear chain of amino acids, with each amino acid representing a build block. The shape of each block depends on the Φ and Ψ angle of each residue. In regular secondary structures these angles are the same for each residue, and thus the shape of each building block, or amino acid, is the same. " - Extended strand secondary structure
